But Jennifer Lopez feels like that's happened to her a LOT when it comes to her love life.

After the 45-year-old dated 27-year-old Casper Smart for a few years, she was often called a cougar. Then more recently, J.Lo's much younger co-star Ryan Guzman in her new flickThe Boy Next Door has prompted relationship buzz.

However, Jennifer wants everyone to know she's NOT dating Ryan and she doesn't like being called a cougar — not one bit!
